This invention comprehends the provision of a tool by means oi which thespring of an engine tappet valve can be easily and convenientlycompressed on the stem of the valve with a view of either assembling ordi assen'ibling the component parts of the valve as the occasion mayrequire.

In carrying out my invention, I contemplate a tool capable of beingquickly adjusted to accommodate itself to diii'erent size valves, whilethe component parts of the tool itself can be easily disassembled so asto occupy a minimum of space in a tool kit or the like when not in use.i

Another and very important object of the invention resides in theprovision of a. tool of the class in question designed to effectivelyengage and support the valve while the tool is in use.

The nature and advantages of the invention will be better understoodwhen the 101- lowing detail description is read in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a perspective View ofthe tool forming the subject matter ofmy invention.

Figure 2 is a side elevation showing the manner of using the tool.

While the invention can be practiced in a general way it is particularlyuseful and advantageous for compressing the spring of a valve whenarranged in the head of the engine, and is therefore primarily designedfor use in this connection.

The tool essentially embodies a base 10 preferably in the nature of anelongated fiat bar, one end of which is upturned to provide a flange 11.Bolted or otherwise suitably secured to this flange 11 is a standard 12,the latter being twisted at an appropriate point in its length asillustrated to arrange the lower portion of the standard parallel withthe flange 11. The standard 12 is provided with a plurality of spacedopenings 13 to per mit the lever 14 to be pivoted upon the standard atdiiierent points, depending upon the size of the particular valve to "bedealt with.

The handle 14 is formed from a single piece of material oichannel-shaped formation in cross section tor the major portion of itslength, although the handle is bifurcated at one end and the separatedportions 15 arranged to straddle the upright 12. These separatedportions support a pivot bolt 16,

which as above stated can be arranged in any bolt 18 in the desiredopening 17 of the handle. 1

As above stated the tool is primarily intended for use in conjunctionwith engine "tappet valves, for compressing the spring of the valve tofacilitate the assemblage or disassemblage of the component parts of thevalve asthe occasion may require,

As hereinabove stated the tool is primarily intended for use inconjunction with valves arranged in the head of the engine, and furtherembodies a tubular extension or valve support 20 which is preferablyprovided with a plurality of lugs 21 depending from the lower edgethereof. The elongated base 10 is provided with spaced openings 22 toaccommodate the lugs 21, so that when the valve support 20 is arrangedupon the base, it will be prohibited'froni slipping or moving relativelythepleto or with respect to the valve to be dealt wit In practice thehead of the engine indicated generally at A is arranged upon the base10, with the valve support 20 positioned to engage the head 23 of theparticular valve to be dealt with. The stem of the valve'is indicated at2 1, while surrounding the stem is the usual spring 25, one end bearingagainst the head of the motor and the other end against a washer 26. Thespring is held in position by the usual cross pin 27 which is normallyengaged by the washer 26. After the parts have been arranged in themanner illustrated in Figure 2, the handle 14 is lowered, bringing theyoke 19 into engagement with the washer 26, and upon continued movementof the handle in the same direction, the spring 25 is compressed.Secured to one end of the base 10 is a flexible element, preferably achain 28, which includes a plurality of spaced rings 29, one of which isadapted to be placed over the adjacent end of the handle 1% to hold thelatter in its active position, and the spring 25 in a compressedcondition, thereby permitting the use of both hands to remove the crosspin 2"? from the stem of the valve. After this has been accomplished,the handle 14 is released, and moved upwardly to an out of the wayposition, whereupon the spring and valve can be readily and easilyseparated. The same operation is proceed with when it is desired toassociate the spring with the valve.

As above stated the handle 14 can be adj usted upon the standard 12, andthe yoke 19 adjusted longitudinally of the handle so that the tool canaccommodate itself to different size valves. In addition to this featureof the invention, the component parts of the tool can be quickly andeasily separatedso that the said parts can be compactly arranged withina tool kit or the like and thus occupy a minimum of space. For thispurpose the handle 14 can be removed from the upright 12, and the lattersubsequently separated from the flange 11 so that all three of theseparts can be arranged side by side in parallelism, while if desired theyoke 19 can also be separated from the handie. 14

lVhile it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood thatl do not limit myself to what is herein shown anddescribed, and that such changes my be resorted to when desired as fallwithin the scope of what is claimed.

hat is claimed is:

A valve tool of the character described comprising abase, a standardrising therefrom, a handle pivoted on the standard and arranged abovethe base, a valve spring engaging member depending from the handleandadjustable longitudinally thereof, a tubular valve support, lugsdepending from the support, and said base having spaced openings to receive said lugs to hold the supportfixed relatively to the base when thetool is in use.

In testlmony whereof I affix my signature.

HOWARD n. Connrrs.
